Hi

We've been on the phone for much of today since our own scheduled system upgrade has been completely snarfed by a breakage of what Telkom claims is the cable from Hong Kong to India. Fun to loose a few thousand rand an hour - thanks Telkom.

Evidently they are not interested in routing ADSL traffic to Ashburn via SAT-3 for some reason, infact none of their reasoning makes sense, because its all just haywire at the moment and there is packet loss left right and center.

Will keep this posted if anything at all comes of it.
 
Sorry for x-posting but I just posted the following on this thread. Your post makes me thing that Telkom may be having problems all over the place.

----------

I just called Telkom's ADSL technical support line (0800 375 375) and I was told that the line connecting Rosebank to NY is down and that they are working on it. The people who connect through this line (e.g. users in Pretoria and Joburg) will experience limited or no international connectivity.

Yow, someone got out of bed on the wrong side this morning - and to think, I considered you a person of great integrity and merit. Guess I was wrong. Mental note made. How the f@ck do you know what I'm downloading and what the f@ck I'm doing - your not the only one who works for a living, china.
 
definitely not fixed on my side. still getting pings/tracerts of over 1000ms internationally.

:P

Thanks "china" I've been at work since 7am with a hangover till now twideling my thumbs and listening to people screaming at SAIX over the phone (and listening to them scream back) because it took them about 12 hours to actualy perform corrective rerouting so we could do what we planned to do.
 
I dont understand this "broken cable" crap. Its the same bit of fibre that IS and UUnet uses but those have been hundreds all day.

SAIX have very much not been forthcoming on information here - I can respect that they play broken telephone with various techies along the way but its no excuse for the rudeness my colegues encountered when trying to get to the bottom of it.
 
The break was on the US side of the link between the landing point and the point of presence in the US. It was due to mother nature and the US gov't was restricting access to the area due to safety and security concerns. UUNET actually breaks out of Portugal and routes via Miami on the Columbus cable I think.. Depending on the peering partner in London, the route to the US is different and could be several hundred miles or more apart. Since the SAT3 in theory ends in Portugal, any thought that it is the same cable that IS and others use is incorrect. Do you think IS and UUNET would want to piggy back on Telkom any further than they had to?

They could have found an alternate route earlier though..

They should also not have been rude to anyone on the phone.. But you can imagine by most of the complaining people out there (we see them here all the time) that they were tired (and possibly hungover as well) of all the rude customers calling..

Take a look at http://www.safe-sat3.co.za/ you'll see the cable doesnt go all the way to the USA. Probable another cable system was effected by the failure.

I suspect that this was also not on a link going via SAT3 cause SAT3 goes via the west coast of africa while SAFE goes directly to the east. Check the link below you'll see SAIX has some links via SAFE. My guess is that the pink link (on the saix topology diagram) failed since that goes directly from rosebank to new york

I really know squat about routing etc, but if the break was on the US mainland why were my pings to www.bbc.co.uk equally as poor as any ping to a us server? I would guess to get to the UK we would go SA-Portugal on SAT3 and then on to London, or is all saix international bandwidth routed via the states?

Hi

I'm fully aware of the SAT3's structure, however connections were getting packet loss all over the place, even when routed via Amsterdam. There are also lots of peers out of London, which should have automaticly sorted them self out when the US point broke down - yet this took from 7:00 till around 17:00.

Yeah, I'm sure Telkoms day was as bad as mine if not worse but they sounded like they had zero clue what was going on. An amazing network as they boast shouldnt fall over with a single dead link.

Anyway, the day is over.

Yeah? So what was wrong with the rest of those "links". SAIX claimed they could ping our servers fine from their NOC, yet ADSL couldnt... WTF-HAI2U on that one...
